Abstract: This paper is about the new automatic technique of inbuilt hydraulic jack system. Whenever the tire failure is occurred in the vehicle then to lifting the vehicle from ground surface is the very difficult think for human being and also, huge human effort required and more time taking process. There, this inbuilt hydraulic jack system helps to lift the vehicle from the ground instead of conventional mechanical jack, and saves the time and excess effort. Separate buttons are provided in order to raise or lower the right and left side jacks. By pushing the given button in the dashboard, the inbuilt self-jacking component gets initiated. Main parts of this project are hydraulic jack, master cylinder, valves, manifold, and oil reservoir. The inbuilt hydraulic jack will be valuable to the senior residents and for women who discover it incredibly hard to work the jack physically in any breakdown of the vehicle. This hydraulic jack will have the option to lift the wheels as indicated by our prerequisite that is on the off chance that we need to lift just two wheels, at that point it tends to be finished by moving the cylinder as needs be on the rack with the assistance of the DC motor.

Abstract This paper describes a systematic approach to analyzing manufacturability of parts produced using Solid Freeform Fabrication (SFF) processes with flatness, parallelism and perpendicularity tolerance requirements on the planar faces of the part. SFF processes approximate objects using layers, therefore the part being produced exhibits stair-case effect. The extent of this stair-case effect depends on the angle between the build orientation and the face normal. Therefore, different faces whose direction normal is oriented differently with respect to the build direction may exhibit different values of inaccuracies. We use a two step approach to perform the manufacturability analysis. We first analyze each specified tolerance on the part and identify the set of feasible build directions that can be used to satisfy that tolerance. As a second step, we take the intersection of all sets of feasible build directions to identify the set of build directions that can simultaneously satisfy all specified tolerance requirements. If there is at least one build direction that can satisfy all tolerance requirements, then the part is considered manufacturable. Otherwise, the part is considered non-manufacturable. Our research will help SFF designers and process providers in the following ways. By evaluating design tolerances against a given process capability, it will help designers in eliminating manufacturing problems and selecting the right SFF process for the given design. It will help process providers in selecting a build direction that can meet all design tolerance requirements.

Characteristic feature of ultrasonic densitometry have been investigated in women,s population of Chelyabinsk (n=200) from 25 to 65 years old. We used domestically produced Echoosteometr-02. A basis of a body of the lower jaw became a new area for ultrasonic densitometry. We can recommend a lower jaw as a new area for ultrasonic densitometry taking into account high pithiness of data in a combination with simplicity of research. Traditional localizations have been also applied: proximal phalanges of the hand, patella, tibia diaphysis and calcaneus bones of the right and left sides. We have established a "peak" values of a speed of the ultrasound wave for the given bones. Also we have found that a tubular bones and a large spongy bone - a lower jaw - possess the highest speed of an ultrasound wave, and the speed was mach less in a small spongy bones, that is caused by their anatomic structure. Ultrasound densitometry parameters of the peripheral skeleton start to reduce from 40-50 years behind exception patella - from 55 years. The lowest values were in group of women of 60-65 years. The rates of ultrasonic densitometry received by us are possible to use for women population of Chelyabinsk.

Abstract Andrew Jameton in 1984 coined the concept of moral distress as: “knowing what to do in an ethical situation, but not being allowed to do it” This original description presupposes that the right moral act can be identified and precludes situations of doubt and uncertainty. The 1984 definition emphasizes barriers that make it impossible for someone to do what they ought to do. Whereas Jameton in a revision in 2013 of his original concept emphasized reduction of the psychological dimensions, Peter& Liaschenko stress the element of moral agency. Moral distress then is a threat to the moral integrity of the professional. This requires three-step ananlysis: first, what is the moral question?; two, what are morally adeguate answers to this question?; three, what ethically appropriate actions are under pressure in the given situation? This will be illustrated with examples from the COVID-19 pandemic.

The aim of this publication is to determine the OEE (Overall Equipment Efficiency) indicator for 5 axes milling machine found at Diehl Aircabin Hungary Ltd. for the present and future state. Based on this value, the utilization of the machine for the given production amount can be calculated. With the optimal choice of the right production parameters (the number of cuts, feeding, depth of cut, etc.) greater productivity can be achieved i.e. the machine main time (time of cutting) will be less. The possibilities of the reduction of the machine time will be analysed and calculated. Setting of the appropriate technological parameters the machine main time could be decreased. The calculation of the machine main time will be determined for the most frequent manufacturing technologies.

Soon after its creation, Pakistan confronted many issues including refugee problem, scarcity of able political leadership, absence of mutual consensus between both wings of the country and confusing nature of the relationship between Islam and state etc. took almost nine years to frame the permanent constitution for Pakistan. Constitution, the basic document of a state, determines the shape of its laws, structure of governance and system of rights and duties. The effectiveness of a constitution is judged by its practicability in the given area where it is enforced by the state machinery. Although, all civilized states of the world do possess a constitution, yet a good constitution is one which must protect the basic human rights by ensuring the independence of judiciary. Due to countless hurdles at the beginning of its journey, Pakistan’s constitutional development in the right direction could not take place. The main objective of the present study is to provide deep insight into the events and factors causing a delay in the constitution-making for the newly created state of Pakistan. The various events which took place from 1947 to 1956 have been analyzed in a subtle way.

Right Descending Aorta

The anatomic nature of a double aortic arch is described. Reference is made to the history of the malformation. The clinical picture and radiographic findings described by various authors are discussed. Two cases are reported which demonstrate two types of double aortic arch, One, a relatively common type, had a large right arch with a retro-esophageal component and a left descending aorta; the second, a rare type, had a large left arch with a retro-esophageal component and a right descending aorta. Further, one was an infant who had symptoms of constriction whereas the other was an adult who had no symptoms referable to the double aortic arch. Analysis is made of these cases and 47 other cases reported in the literature. This analysis reveals that: 1. There is a striking correlation between the occurrence of symptoms and the age and duration of life, but there is no correlation between the occurrence of symptoms and the type of double aortic. 2. A double aortic arch in which both components are patent throughout is more likely to produce symptoms than a double aortic arch in which one component is partially obliterated. The process of obliteration does not appear to give rise to symptoms. 3. There is considerable variation in the relative sizes of the components of a double aortic arch. The right component is usually the larger; part of the left component may be obliterated. To date, no case has been reported of obliteration of part of a persistent right Component. 4. A double aortic arch occurs more commonly with a left descending aorta than with a right descending aorta. 5. It is unusual for a double aortic arch to be associated with a malformation of the heart. The association of a double aortic arch with other vascular abnormalities is less rare. The two principal problems raised by the demonstration of a retro-esophageal vessel are discussed. The first concerns the nature of the malformation; the second concerns the advisability of operation in the given individual.

Manufacturing Problems

Increasingly, Solid Freeform Fabrication (SFF) processes are being considered for creating functional parts. In such applications, SFF can either be used for creating tooling (i.e., patterns for casting, low volume molds, etc.) or directly creating the functional part itself. In order to create defect free functional parts, it is extremely important to fabricate the parts within allowable dimensional and geometric tolerances. This paper describes a systematic approach to analyzing manufacturability of parts produced using SFF processes with flatness tolerance requirements on the planar faces of the part. Our research is expected to help SFF designers and process providers in the following ways. By evaluating design tolerances against a given process capability, it will help designers in eliminating manufacturing problems and selecting the right SFF process for the given design. It will help process providers in selecting a build direction that can meet all design tolerance requirements.

In this article, in the sequel of extending b-metric spaces, we modify controlled metric type spaces via two control functions α ( x , y ) and μ ( x , y ) on the right-hand side of the b - triangle inequality, that is, d ( x , y ) ≤ α ( x , z ) d ( x , z ) + μ ( z , y ) d ( z , y ) , for all x , y , z ∈ X . Some examples of a double controlled metric type space by two incomparable functions, which is not a controlled metric type by one of the given functions, are presented. We also provide some fixed point results involving Banach type, Kannan type and ϕ -nonlinear type contractions in the setting of double controlled metric type spaces.
